Is there a way to have log and share files saved to the computer much like cgminer does? If so what is the command i need to add to batch file?

No specific logging yet. But as cudaMiner will always have an identical feature set to pooler's cpuminer (like for example the stratum support), you might want to direct such wishes at the maintainer of the cpuminer project. This is pooler himself (he also has a forum account here, and his project is also on github where you can make feature requests).

I'm currently experiencing something weird with cudaminer. Khash/s jumps a lot, from being stable at 165 Kh/s to sometimes hashing at 160, 155, 80, 140, and so. Launch config at 70x2 then autoconfig. Still weird.

have you tried running with -i 0 ?

Not yet, because I've been using the computer while mining, but I hadn't seen that happen before. I will try and post back with results.

Also, trying with -l 35x4 certainly gives more stable results, but hashrate is a little lower. I get 155 kh/s give or take with it.

Edit: Just switched to -i 0 -l 70x2, and cudaminer's back to 165+ kh/s stable. It didn't need the -i 0 switch before, but the PC's still responsive enough to use while mining, so all is good, I guess. If only the GTX 670's fan didn't sound like a jet engine...

some newer GT730M now ship based on the newer GK208 die - Meaning they have a barrel shifter that accelerates SHA256 and scrypt, and these can use 255 registers per thread. Currently expect around 40 kHash/s in scrypt from these models - I am planning to optimize the code further. I think 60-80kHash might be achieved.

Okay, now I have a new cudaMiner windows binary with working stratum protocol. It just took less than 90 minutes to put all my CUDA related changes into pooler's code. I will need a few more hours to package a nice release version. Linux compilation may currently be borked. I was focusing on a clean Windows/Visual C++ port of the original cpuminer code, so testing compilation on Linux was not a priority.

No changes were done to the CUDA parts, I simply inherited stratum and other small fixes from pooler's latest cpuminer 2.3.2 release version.

Check the README.txt file for an example on the stratum URL syntax. I successfully tested this on coinotron.com.

I still take donations

P.S. The next steps will be:a) cleaning up the CUDA code and modularizing it better.b) I intend to improve the performance of the Titan kernelc) add back the old "special" kernel for legacy devices (compute 1.x).

Testing the new release with stratum mining and pleased to report that my stale shares are practically no more! Will keep it running some more, but feeling confident that this bugbear has been dealt with.

I think there is 3% increase of hash rate. Thanks! I still see problems (stratum timeout adn reconnection) that arre probably related to network with coinotron. But the stale rate should be lower. Haven't had enough shares to prove it.For pools that have variable difficulty, can the new cudaminer show share difficulty?

+1 its great to finally get stratum but after the headache of getting the proxy to work it was nice to see the share diff

I cannot really answer such questions appropriately, as I haven't written this code. Any bug report directed to pooler will help him fix his implementation, which in turn can be merged into cudaminer within a matter of days.
